    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.

u/lewdev

Cool stuff. It breaks on capitalized letters though. Add a.keyCode==16?0: into the start of your onkeyup method, which allows the shift key to be pressed.

u/vain

Nice!
u/vain

Btw... shouldn't "[i%5]" be "[i%6]"? Else you could save 1 char. :) What do these three points mean you used here: "fillText([... ,'" ?
u/BriSeven

Whoops, you're right. The ... is the spread operator, it splits the string in a unicode friendly way, and assigns the individual characters to the enclosing array literal.
u/BriSeven

@vain do notifications work on dwitter?
u/BriSeven

the ... next to the string is actually a special case. more generally it works on anything that implements the "iterator protocol" which is lots of stuff, but mostly arrays and array like things.
